Abstract
OBJECTIVE: To test the hypothesis that the continuous infusion of papaverine-containing solutions in peripheral arterial catheters would decrease the catheter failure rate and increase the functional duration of the catheter in neonates. STUDY DESIGN: In a prospective, randomized, placebo-controlled, masked trial, 82 catheters were placed in 70 neonates in the papaverine group and 98 catheters were placed in 71 neonates in the placebo group. RESULTS: The catheters in the papaverine group remained functional for a significantly longer duration than those in the placebo group. The median (25th%, 75th%) time before catheter failure was 16.6 (9.5, 24.3) days in the papaverine group and 12 days (6.1, 18.2) in the placebo group ( P = .023; Cox proportional hazards model). There was no significant difference in the incidence of intraventricular hemorrhage (IVH) between groups, and there was no evidence of hepatic toxicity. CONCLUSIONS: The continuous infusion of papaverine-containing fluids prolongs the patency of peripheral arterial catheters in neonates. In this small number of infants, we found no difference in the incidence of IVH or hepatic toxicity.
